Abstract
The utility model discloses a three-point lifting beam which comprises stayed wire slings and a supporting beam. Both ends of each of the stayed slings are provided with grommets. The three-point lifting beam is characterized in that the three-point lifting beam also comprises two end part connecting heads and a middle part connecting head; after the supporting beam passes through the middle part connecting head, both ends of the supporting beam are respectively fixedly connected with one end part connecting head; the upper ends of the two stayed wire slings are connected with a lifting hook of a crane through the grommets and the lower ends of the two stayed wire slings are respectively connected with the end part connecting heads; and after passing through the middle part connecting part, a middle wire sling is hung at both sides of the lifting hook of the crane through grommets at both ends of the middle wire sling. The stayed wire slings are directly connected at both the ends of the lifting hook and the supporting beam, and thus, in the lifting process, the middle part connection head is regulated so as not to be contacted with the supporting beam, so that a middle lifting point does not generate an acting force on the supporting beam. The supporting beam is only acted by the centripetal extruding force, and thus, although one more lifting point is increased, the weight of the supporting beam can be reduced. When being lifted, the lifting beam has the load bearing capacity of 200 tons.
Description
Technical field
The present invention relates to a kind of hanging beam of weight-lifting equipment, especially relate to a kind of bikini hanging beam of lifting main equipment.
Background technology
During the lifting of main equipment; Need to adopt balance hanging beam or distribution beam to increase suspension centre; The ZL201010555949 Chinese invention patent; Disclose a kind of many suspension centres suspender that is used for nuclear station module lifting, this patent has adopted the two-stage hanging beam for increasing suspension centre, its shortcoming be the volume of suspender own big, from great.
Summary of the invention
The purpose of the utility model provides a kind of lightweight bikini hanging beam own, and the utility model is achieved in that a kind of bikini hanging beam, comprises oblique rollering steel sling wire, support beam, and the said two ends of hoist cable of tiltedly drawing are provided with grommet.It is characterized in that: also comprise two end connectors and a middle part connector, after said support beam passes the middle part connector, each affixed end connector of its two ends; The upper end of two oblique rollering steel sling wires is connected with the suspension hook of crane through grommet, and its lower end is connected with the end connector respectively; After a process wire hoist cable passes the middle part connector, hang over the both sides of hoist lifting hook through the grommet at its two ends.
The sidepiece of said end connector is captiveed joint with support beam, and its downside is provided with and following wire sling bonded assembly pulley, and the corner portion between wherein is provided with pivot pin, and this pivot pin is connected with the grommet of oblique rollering steel sling wire is nested.
Said middle part connector is made up of upper pin connecting portion, intermediate regulations portion and lower sheave connecting portion; The centre of said upper pin connecting portion is provided with the bearing pin that supplies the process wire hoist cable to pass, and the lower sheave connecting portion is provided with the pulley that passes with following wire sling, and said middle part connector is connected upper pin connecting portion and lower sheave connecting portion.
Said middle part connector is two blocks of steel plates that are positioned at both sides, and steel plate is provided with the screw of vertical arrangement, and will go up connecting portion through bolt and fix with following connecting portion.
Said down wire sling is that two ends are provided with suspension ring, and passes pulley and be connected with the hanger of suspended object.
The utility model compared with prior art; Have the following advantages and beneficial effect: because oblique rollering steel sling wire direct connection is at the two ends of suspension hook and support beam; Regulate the middle part connector during lifting, the middle part connector is not contacted with support beam, suspension centre does not produce application force to support beam in the middle of making.The application force that support beam is suffered only is a squeese pressure entad, therefore, though increased a suspension centre, has improved load-carrying capacity, and the weight of support beam can alleviate; Load-bearing when hanging beam of the present invention is sling is 200 tons.

Specific embodiments
Bikini hanging beam of the present invention is to be design-calculated hanging beams such as construction nuclear station, large-scale ship and offshore platform, and its load-carrying reaches 200 tons.Said bikini hanging beam is made up of two oblique rollering steel sling wires, process wire hoist cable, three following wire slings, support beam, two end connectors and a connector of merely hitting.The two ends of said oblique rollering steel sling wire, process wire hoist cable and following wire sling all are provided with grommet.After said support beam passes the middle part connector, each affixed end connector of its two ends, the upper end of two oblique rollering steel sling wires is connected with the suspension hook of crane through grommet, and its lower end is connected with the end connector respectively.The sidepiece of said end connector is captiveed joint with support beam, and the center is provided with the pivot pin that passes with the oblique rollering steel sling wire, and its downside is provided with and wire sling bonded assembly pulley.
After a process wire hoist cable passes the middle part connector, hang over the both sides of suspension hook through the grommet at its two ends.Said middle part connector is made up of last connecting portion, middle connecting portion and following connecting portion; Said centre of going up connecting portion is provided with the bearing pin that the arch wire sling passes, and following connecting portion is provided with and wire sling bonded assembly pulley, and said middle connecting portion will be gone up connecting portion and be connected with following connecting portion.Wherein, connecting portion is two blocks of steel plates that are positioned at both sides, and steel plate is provided with the screw of vertical arrangement, and will go up connecting portion through bolt and fix with following connecting portion.The screw of vertically arranging is used for regulating, and is when making lifting, makes the middle part connector not produce application force to support beam.
Said wire sling down passes pulley, and its two ends are connected with the hanger of suspended object.Because all there is grommet at the two ends of following wire sling.Therefore, suspended object is when the design hanger, and each suspension centre can be provided with two hangers, and three suspension centres can be provided with six hangers, and the load-carrying ability of the utility model is improved greatly.
